IMPROVED @LR-WASHER..

TO ALL WHOM IT MAY CONCERN:

Be it knownthat I, I. F. Qmlvmnotf Rochester, in the county ci' Monroe, and State of New York, have invented a new and useful Gold-W'asherg" and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to theaccompanying drawing,'makiug part of this speciiication, in whichl The figure is a vertical central section of' my invention, showing the relative arrangement of the various parts.

.'This invention is designed more especially for placer oir-dry diggings, and its nature consists in the employment of acounter lcurrent of clean water passing through the descending goldbeariug sand or earth, whereby all the/fine earthy or organic matter is oated olf and a thorough separation eifected by a suitable revolving beater or agitator.

To enable others to make and use my invention, I will describe its construction and operation.

The base or chamber A is designed to receive the gold and clean sand from the cleansing tube G. It may be provided with several large cocks J, at different elevations to draw, oil` the iuid portion when the chamber is to be emptied, also-a mane-hole, H, through which to remove the gold and sand. The induction water-box B, is bolted to the top 'of the chamber A, and sustains the cleansing tube G by a editable packed joint, a. The supply water tube T discharges through the outer shell of the vwater-box B, which is provided with`an inner drum or cylinder, cl, having a series oi` slots or openings, z', by means of which the water is introduced from all sides. The tube l leads from a suitable reservoir, R. The cleansing tube or pipe G gradually increases in size from 'the water-box to its junction with the agitator section or ease D, which may be twelve inches, moreor less, in diameter` The tube Gr maybe six feet in length, more er less. There isla series of four armed heads, h, keyed or attached by set-screws to the pulley shuitf, which has its bearings in the smiling-boxes Zi, and may be provided with a loose and a tight pulley, p undp. The bcll-topped tube E 'is belted to tbetop of case D,

and extends upward six feet, more or less, and is providedat the top witha broad spout, S, slightly descending to a. collecting or settling-pan, P. The tube E is slightly contracted toward the top, and within this tube is suspended the feeder tube C, having a suitable funnel top. ,This tube is suspended within the tube E; leaving an annular space between them of one-half inch, more or less. It is of the same taper ais-E, and extends from the bottom oft to ten feet, more or less, above its top., The Water tank R is placed at a suitable elevation above the equalizing or displacing tubejE. The pipe T may be about three inches in diameter, and the quantity of water used would depend upon the elevation of the fountain It, being less for a greater height, and vice vea-sla. This may be regulated by the gate g. The upper portions of the apparatus may be sustained in a derrick or framework. The gate g is'raised by drawing the cord lc, which may be extended to the ground, as may also the cord m used for closing the gate. The chamber R being filled, and also the tubes up to the spout S, the earth 0r send' to be washed is thrown into the funnel y, anddesc'ends to the revolving mixer or agitator, by the action of which it is reducedto a ne disintegrated condition, whenv all the heavier particlesv of gold or sand will settle through the gentle upward current of water, while all the earthy and organic` matter and' the 'very line particles of gold or gold-dust will be carried up by the current and float o' into the settling-pan, shown by dotted lines. When the-chamber A becomes iilled or nearly so with'thc washed sand and gold, the water is drawn oil' and the solid deposits removed to the amalgnmator or other apparatus for separating the gold from the sand.

What I claim Aas my invention, and desire to secure by Letters Patent of` the United States, iss-- 1. Passing the gold-bearing sand or other material to'be washed through an upward or counter-current of water, for the purposes herein shown and described. l

2. The employment of the agitator, constructed, arranged, and operating in combination with the tubes E,

C and G, substantially in the manner and for the purposes set fortb. i

3. The water-box B, when constructed, arranged, and operating conjointly with the `deposit-chamber A, and the supply or inductiontube` T, and the "ertical discharge pipe G, for the'purposes set forth.

I 4. The general construction and arrangement of all the parts, substantially in the manner and for the pur;

posesV herein shown anddescribed.
